BOBBIN-STRIPPER.

Application iled May 1G,

.To all whom t may concern.'

Be it known that I, CLARENCE A. PIERCE, a citizen of the United States, and resident V`of Lowell, county of Middlesex, State of accompanying drawing, is a specificatiom' like characters on the drawing representing like parts.

This invention relates to bobbin strippers of the type which strip the bobbin by reeling the yarn therefrom, and it has for its object to provide an improved stripper of this type which is simple in construction and effective in operation. Y

In order to give an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.

In the drawings:

Figure 1 is a side view of a bobbin stripper embodying my invention.

Fig. 2 is an edge view showing the comb.

Fig. 3 is a section on the line 3-3, Fig. 1.

A bobbin stripper embodying my invention comprises a receptacle to receive the bobbins to be stripped, a spindle rotatable about a horizontal axis and situated above the receptacle and adapted to have the yarn ends wound thereon, and means interposed between the spindle and the receptacle to prevent any bobbins which may be lifted from the receptacle from being wound up on the spindle.

The bobbin receptacle is indicated generally at 2 and the spindle is indicated at 3. These parts are supported by a suitable frame 1 and the spindle is situated above the receptacle 2 and is carried by a horizontal shaft 4 which maybe driven by any suitable means such as a belt pulley 5. The bobbins to be stripped are placed in the receptacle 2 and the loose ends from the bobbin are gathered together and connected to the spindle 3 so that as the spindle 3 rotates such loose ends will be wound thereon. The winding of the yarn ends on the spindle will tend to lift the bobbins slightly` from the receptacle 3 and the yarn ends will thus be unreeled from the bobbins and wound up on the spindle.

In the operation. of the device it frequently happens that the yarn on some par- Specicatien of Letters Patent.

ticular bobbin will become caught so that instead of unreeling from the bobbin as the spindle 3 is rotated the bobbin will lbe lifted up by the end and will be carried to the spindle and wound thereon. To prevent this I have interposed between the spindle and the receptacle a suitable device which allows the yarn ends to 4pass freely from the receptacle to the spindle but which prevents the passage of bobbins. rlhis device may assume different shapes and forms without departing from my invention but one convenient construction is that herein shown and which is in the nature of a comb. It comprises a bar 6 extending laterally from the frame 1 and preferably parallel to the spindle 3,y said bar being situated below the spindle and between the latter and the receptacle 2. This bar 6 is provided with a plurality of pins or fingers 7 extending laterally therefrom, said lingers being spaced apart a distance less than the diameter of the bobbin.

In using the device the operator will gather together a large number of loose ends from the bobbins in the receptacle 1 and will carry said loose ends up to the spindle and will attach them thereto as the spindle rotates, said loose ends being carried between the fingers 7 as shown in the drawings. As the spindle 3 rotates the yarn will be unreeled from the bobbins but some o f the bobbins will be lifted out of the receptacle due to the yarn thereon becoming caught or snarled.V Such bobbins as are lifted as high as the comb will be prevented by the the yarn on said bobbins is still snarled so.

that it does not freely reel off from the bobbin when the latter is stopped by the fingers 7, said yarn will become broken allowing the bobbin to drop back into the receptacle 2.

This comb, therefore, provides an en'icient means for preventing any bobbin from being carried up by the threads and wound onto the spindle 3.

I have found from practice that this device will effectively strip or clean the yarn from practically all the bobbins which are placed in the receptacle 2.

The receptacle 2 is shown as having a removable bottom 8 and as being supported above a second receptacle 9 which is removable. In operating the device a number of bobbins, say three or four hundred, will be placed in the receptacle 2 and will be operated on by the machine to strip the yarn therefrom. Then the yarn has been reeled off from all the bobbins then the bottom S is withdrawn allowing the bobbins to fallv into the receptacle 9 after which the bottom is replaced and a fresh lot of bobbins to be stripped may be placed in `the reeeptacle. The receptacle 9 may then be removed and an empty receptacle 9 placed in its stead.

I claim.

l. In a bobbin stripping machine, the combination with a receptacle to contain bobbins to be stripped, of a rotatable spindle above the receptacle and adapted to have the yarn ends from the bobbins wound thereon, and a device interposed between the spindle and receptacle to prevent any bobbins which may be lifted from the receptacle from being wound on the spindle.

2. A bobbin stripping device comprising a receptacle to contain the bobbins to be stripped, a rotatable spindle above the receptacle adapted to have the yarn from the bobbins wound thereon, and a comb device situated between the spindle and the reeeptacle and through which the yarn ends pass awayto the spindle.

In testimony whereof I have signed my name to this specification.
